FREDERICK W. HOCHSTETTER, OF NEW YORK, N. Y.

CONVERTIBLE MOVING-PICTURE MACHINE.

Application led December 4, 1913.

To all 'whom t may concern.-

Be it known that I, Fanonnicn W. Hoens'rETTEn, a subject of the Emperorof Germany, and a resident of New York, county and State of New York,have invented a certain new and useful Improvement in ConvertibleMoving-Picture Machines, of which the following is a full, clear, andcX- act specification.

This invention relates to a class of machines adapted to be used forphotographing pictures upon a strip, and subsequently' employed fordisplaying the pictures upon a screen.

My invention h as for its object primaril to prov1de a movin picturemachine whic may be converted rom a camera to a projecting apparatuswhereby a series of pictures of the mot-ion acts of living objects, orscenery may be photographed in succession upon a strip and afterwardconsecutively display upon a screen, in order to obviate the use of twoseparate machines as is incident to methods usually employed in theproduction and exhibition of moving pictures.

Another object of the invention is toprovide a machine designed to beemploye especially for producing the picturesupon a strip f paper, orother opaque material which is ordinarily considered as beingnoncombustible, and then using the same ,machine for projecting thesepictures.

Other objects of the invention are to provide a number of incandescentlamps adapted to be employed when the pictures of the strip aredisplayed upon a screen; lto provide a reflector of a form which servest0 deflect the rays of .light from the lamps upon the pictures whenbeing transmitted through the machine; to provide two separatc electriccircuits, one adapted to supply the Ylamps with a current from anysuitable source ot' supply and the other'being adapted to suppl v thelamps with a current supplied from batteries mounted m the machine. andto provide two adjustable lens barrels. one carrying a lens forphotographing objects and the other carrying a lens for Specication ofLetters Patent.

projecting the pictures whereby the machine may be readily convertedfrom a camera to a projecting apparatus or vice versa. \V1th `these andother objects in vieu, the invention will be hereinafter more particularlytlcscribcd with reference to the accompanying drawings which form`a part of this specification, and will then be pointed out in theclaims at the end of the description.

In the drawings, Figure 1 is a perspective view, partly fragmentary, ofone form of convertible moving picture machine embodyrn my invention.Fig. 2 is a top plan, partly roken away, of the machine. Fig. 3 is anenlarged sectional view, partly broken away, and partly fragmentary,taken on the line l'I--II of Fig. 2. Fig. 4 is a View through the upperpart of the extension of the casing of the machine, showing thearrangement of the lamps used for supplying light to the'machine. Fig. 5is a sectional view, partly fragmentary and partly in detail, taken onthe line III-III of Fig. 4. Iig. 6 is a diagran'unatic view of theelectric circuits used in conjunction with the' machine. Fig. 7 is anenlarged detail view, partly fragmentary and partly in section, of aforml of shutter employed in the machine. Fig. 8 is an enlargedsectional view, partly in detail and partly fragmentary, ot' themechanism for intermittently checking the transmission of the stripthrough the machine. Fig. 9 is an enlarged view looking at one end ofthe checking mechanism, and Fig. l() is a fragmentary view of the formof the strip on which the pictures are produced. The convertible movingpicture machine has a casing 10 which is preferably rectangular in shapeto provide a bottom 11, side wallsl'Z and 13, a top wall 14, and a rearwall 15. The front end of the casing 1() is open, and within the casinga slight distance from its open end is provided a vertically disposedpartition 16 having an exposure window 17 tlierethrough. Detachablyconnected by means of any suitable forms of clips, as 1%, to the open`end ol the casing 10 is an extension i9 having a bottom Q0, a top wall21, side walls and 23, and a front Wall 24 whereby the interior of theextension will be in communication with the open end of the casing.Through the front wall 24 of the extension is an o vlening 2 which is inregister' with the expdsure window 17 of the partition 16' of thecasing, and on top of the casing 10 may be provided a handie, as 26, topermit the machine to be conveniently carried by a person.

ln order to permit the machine to be conveniently used as a camera, oras a project ing apparatus, I provide two telescopic barrels, as 27 and28, in one of which is mounted a suitable lens 29 for use whenphotographing the motion acts of living objects, or scenery when themachine is use d as a camera, andy in the other barrel 1s mounted asuitable lens 30 adapted to be used for displaying the pictures upon ascreen when the machine is used as a projccting apparatus. Thetelescopic barrels may be of any desired forms so as to be adjustablylengthened or shortened in the usuall manner by manipulating anadjusting screw, as 31. Both of the lens barrels 2? and 28 are held to asubstantially Vshaped plato 32 the apex portion of which is pivoted, as

233, to the front Wall 24 of the extension 19 so that the lens barrelsmay be alternately swung in register with the opening 25 of theextension for permitting light to be focused hy the lenses through thisopening and through the exposure Window 17 of the casA4 ing 10. Topermit the upperv part ol ti e plate to be movably retained against thefront wall of the extension, upon said front wall is )rovided a guide 34which is cour posed ci a curved plate 35 having a curved flange 36depending from its lower edge so as to be spaced fromv the front wall24. to provide a groove 37 in which theupper edge part of the swingingplate 32 is movably inserted. By prrwiding the two lens barrels in thismanner the machine may be readily employed as a projecting apparatusafter being used as a camera or v1ce versa, thereby overconling thenecessity for providing separate lenses and applying them to the Ina--chine as would he required if only one barrel was provided.

The machine is operated by a common drive shaft 38 which is journaled inbrackets `39 provided upon the bottom 1.1 interiorly of the 'casing 10,and the drive shaft is driven` by the rotation of a crank handle 40 heldupon one end thereof. On the drive shaft 39 is a drive gear 41 which isin mesh with a gear 42 held upon a shaft 43 journaled in brackets 44secured upon the bottom of the casing 10, and on the shaft 43 a deliveryreel :34 which is rigidly held on the shaft so to be rotated therewith.The delivery reel 54 is wound with a strip of a formation having spacedmarginal perfor-ations.

vided interiorly of the casing 10.

as 56 and 57 Fig. 10, similar to the usual forms of transparent movingpicture films, and said strip is preferably made of paper, or otheropaque material which is ordinarily considered as beingnon-conibustible, thereby permitting the use of the usual inflammablelms to oe dispensed with. Wr hen the machine used as a camera forphotographing objects ay sensitized form of the strip is employed forproducing the negatives ot the pictures. From the delivery reel 54 thesensitized strip is guidelil over an idler and between two compressionrollers 59 and 60, the idler and rollers being suitably pro- From thecompression rollers 59 and (5() the strip is directed between twocompression rollers 61 and 62 rotatably held to the partition 16 aboveits exposure window 17, and the strip is passed through a framingdevice. as 63, of any well known. form which is provided interiorly ofthe casing 1.0 for yieldingly holding the strip intermittently inregister with the yWindow 17 so that parts of the strip may he exposedconsecutively to rays of light when producing the negatives of thepictures. The strip is then guidedbetween two compression rollers (liand65 which are rotatably held to the parti ion 1G below the framing device(33, and tile strip is aassed over a sprocket drum GFS held u pon atubular shaft (3.7 which is journaled iu the bearing oi a bracket 68provided in the easing l0.. The tubular shaft (3Ty and thc sprocket drum66 are freely rotatable upon a shaft journalel in lspaced hracl-iets G3iand pro vided in the casing and on one end oi said tubular shaft heldadisk Gdroi a device G8@ which serves to intern'nttentlv check therotation oi' the sprocket drum (3G for intermittently checking thetransmission of the strip 55 through the machine. Projecting from oneface of the disk (38d are a number of spaced pins 68" which are in thepath of movement of arms 68g and GS extending radially in oppositedirections from the periphery of a gear @Si rotatable upon a stud (581held in a hracliet G8 provided in the casing. The gear 68 is in meshwith a gear 68* held upon the shaft 68a so that when this shaft isrevolved its rotation will be imparted to the Gtl and S. The arms 68gand 68 Will in turn he sw nog si swessivelv in Contact with the pins 68of the disk 63d, and the sprocket drum will thereby he intermittentlyrevolved. F rom the drum G6 the strip is directed over au idler G9rotatably held to a spring 'TO 'for yieldingly disposing the idlertoward a receiving reel 70n upon which the strip with the negatives ofthe pictures photographed thereon is ",vound. The receiving reel 70"*held upon a shaft 7l journalcd in l ets '.73 provided i the casing 15hand on this siait sprocket is also held a gear '73 which is in mesh withthe drive gear 41. vAlso in mesh with the gear 73 is a gear 74 held upona shaft 75 )oumialetl in brackets 76 extending from the partition 16 ofthe casing 10. On the shaft is a sprocket wheel 76al over which isguided a sprocket chain 77,- and the sprocket chain is passed over asprocket wheel 78 provided upon the shaft 68 of sprocket drum 66. Bythis construction of mechanism, and when the machine is used as acamera, the sensitized strip will be intermittently trans mitted fromthe delivery reel 54, past the window 17 for producing the negativesand' will be rewound on the receiving reel 7()a when the drive shaft 38is driven by rotating the crank handle 40.

For the purpose of intermittingly cuttingoff the light during theexposures of the sensitized film, I provide a shutter, as 79, which isoperated in unison with the operation of the strip transmittingmechanism, as above described, by providing on the shaft 67 a secondsprocket wheel 80, and over the sprocket wheel 80 is guided a sprocketchain 81 which is directed over a sprocket wheel 82 rotatable upon abolt 83 projecting from a bracket 84 fastened to the side wall 13 of thecasing. The shutter TD may he of any well-known type, but I prefer toemploy a form of shutter composed of a disk 85, and from one part ofsaid disk extends a'bar 86. The bar 86 intex-mediate its ends ispivotally held, at 87, to the .partition 16 of the casing, and eX-ten'ling at a right angle from the free Vend of said bar is a finger 88.To the finger 88 is attachedone'end of a spiral spring 89 having itsother end connected to a rod 90 provided upon the side Wall' 13 of theCasing. The spring 89 is tensioned so as to hold the finger 88 wherebythe bar 86 will be disposed on a direct line transversely of thepartition 10 for normally positioning the disk before the exposurewindow 17, and to limit the upward movement of the disk, extending fromthe partition 16 is a stop, or pin 91 for the disk to abut against.Serving to move the finger 88 and the har 86 against the tension of thespring 8f) to intermittently swing the disk 85 from the exposure window17, upon the bolt 83 is provided a trip 92. The trip 92 has a plate U3held to one face of the sprocket wheel 82 so as to be rotatedsimultaneously therewith, and projecting from said plate are a number ofspaced pins 94 which are circumferentially arranged with relation toeach other. The finger 88 of the bar 86 is disposed in the path ofmovement of the pins Utof the trip so that when revolved the pinsthereof will consecutively Contact with the finger 88 for directing ituyuvardly, and the bar 86 and disk 85 will in turn be swung in adownwardly direction away from the exposure window, as indicated bydotted lines at 95.-

When the machine is employed for pro- )ect-ing the pictures of the strip55 on a screen after the negatives are produced, as above described,have been developed, the strip is intermittently transmitted through themachine in a manner similar to its transmission therethrough whenoperated as a camera, excepting that the strip instead of being guidedbetween the compression rollers 61, 62, through the framing device 63,and between the compression rollers 6l, 65 is guided through an openingin the upper part of the partition 16 over the compression roller 6l,then through a suitable second framing device 96 which is also providedupon the partition 16, and the strip is guided over the roller 64, overthe sprocket drum 66 to the receiving reel 70". The machine is therebyadapted to be used for transmitting the strip for displaying thepictures thereon with equal facility t( its employment as a camera, andin order to provide eflicient lighting means for projecting the picturesof the opaque strip 55 upon a screen, I provide a reflector' 97, and anumber of electric lamps,` as 98.

The reflector 97 is of an annular cupshaped formation having an opening99 centrally therethrough in which is mounted one end of a metal tube100. The other end of the tube 100 is secured to the inner surface ofthe front wall 24 of the eXtension 19 of the casing 10 so that thepassage through the`tube is in register with the opening 25 of saidextension and also in register with the o ienings through the framingdevice 93 :wd with the exposure window 17 of the 3 rtition 16. At spacedintervals concentricadv through the reflector 97 are a numbe ,ofthreaded openings t in each of which is screwed the socket of one of theelectric lamps so that all of the lamps are in opposed relation to thepictures of the strip when intermittently exposed through the opening ofthe framing device 96, and said reflector is disposed to adapt it todeflect the rays vof light from the lamps upon the pictures of theopaque strip. In this manner the pictures of the strip will be projectedthrough the passage of the tube 100, through the opening 25 of' theextension. and through onel of the lens barrels 27 and 28.

The electric lamps 98 may be of the usual, or any preferred types, andthe sockets of said lamps extend through the threaded openings of thereflector 97 so that the contacts thereof are imposed against an annular metal plate 102 provided upon the i'rout wall of the extension 11iof the casing. The lamps 98 may be lighted by currents sup plied theretoover Separate electric circuits, as 103 and 104. The electric circuit103 consists in providingone, or a plurality of drycell batteries 105 ofany suitable makes which are carried in an. inner housing 106 arrangedin the casing 10 of thev machineu The housing,y 100 is formed of metal,and each of the batteries 105 is provided with two poles, as 107 and108. The poles 107 of the batteries are disposed in contact with themetal housing 106, and on said housing is rovided a binding post 109. Incontact wit the poles 108 of the batteries is a metal strip 110 providedwith a binding postY 111. which is insu lated from the metal housingl.To the binding post 109 is connected one end of a wire 112 whichterminates adjacent tof'the front end of the casing 10 With'one contactmember of a knife switch 113, and to the binding post 11.1 is connectedone end of la.; wirelli which also terminates adjacent-to the front endof said casing with one Contact member of a knife switch 115. Theknifeswitches 113 and 115 are of the ordinary types cornposed of twointerfitting contact members, and said switches are interposed in thewires for permitting make and brake contacts to be made in the'ci'rcuit103 so that the extension 19 may be detached from the casing lO. Abranch of the Wire 112 extends into the eX- tension 19, and on the endof this branch of the wire which is opposed to the first contact memberof the knife switch 113 is provided the second contact member of saidswitch, The opposite end of this branch of the "wire 112 terminates witha contact 116. A branch of the wire 111 likewise extends into theextension 19, and on the end of this branch of the wire which is opposedto the first contact member of the knife switch 115 is provided thesecondscontact member of said switch. The opposite end of this branch ofthe wire 11-'1 terminates with a contact 11T. In the electric circuit103 are also provided two contacts 118 and 119. Connected to the Contact118 is one end of'a wire 120 leadingy in a wire 121 connected to themetal plate 10". against which is imposed the sockets of the lamps 98,and to the Contact 119 is connected one end of a wire 122 loading to themetal tube 100 ot the reflector 97, The contacts 110, 11T. 118. 119 arerelatively posi- -tioncd in spaced parallel arrangement so that theirfret ends are disposed on the curvature of a circle.

The circuit 101 designated to supply' current to the llamps 9S from any1suitable source of supply, in order to allow the batteries 103 to brdispensed with as occasion requires. The circuit. lill consists in`providin;r a nictal steld-t 123 on the top 2l ol' thc cxtensifm 19 oi?the casing' 10, and thisl .socket has tvfo spaced metal tubular posts121 and 125 extending through openings in thc top of the extension.Connected to the post 121 interiorly of the extension is one end of acontact 126, and connected to the post 125 also interiorly of saidextension is another contact 127. The tubular posts 124 and 1Z5'areadapted to receive, respectively, the contacts 128 and 129 of aremovable plug 130 connected on one endA of cach of two wires 131 and132 leading' from any source of electricity supply other than thebatteries 105. Also interiorly of the extension 19 is a third contact133 one end of which is connected to a Wire 131 leading to the metaltube 100 of the reflector 97. A fourth contact 135 is provided in saidextension, and from one end of this Contact leads a Wire 136 to thewire'go 121 and the plate 102 of the lamps. The contacts 120, 127, 133,135 are relatively positioned in spaced parallel arrangement so thattheir free ends are disposed on the curvature of a circle, and the freeends of these contacts are in spaced opposed relation to the vfree endsof the contactsA 116, 117,118, 119,

respectively, as shown.

Serving to permit the electric circuits 103 or 101 to be hseparatelyclosed` I provide a switch, as 137'. The switch 137 has a post 138 whichis rotatably as well as slidably disposed through an elongated slot 139providu ed in the top 21 of the extension 19 of the casina` 10 midway'between the contacts 116, 117, 118, 119 and contacts 120,127, 133, 135of the electric circuits. On the lower end of the post 138 interiorly ofthe extension 19 is held an insulating plate 140, and mounted on thisplate are two contacts 141 and 142 which alie in the forms of metalblades projecting in similar directions from the insulatingr plate, andboth of these contacts have the free ends thereof curved to conform withthe curvature of the ends of each set of the conmete 116, 117,118, 119and 126, 127,133,135. Onthe upper end of the post 138 of the switclf'andabove the top of the extension 19 is provided a handle 143 forpermitting the switch 13T to be manually operated. v

When it is desired to light the lamps 98 by a current supplied over thecircuit 103 from the batteries 105, the switch 137 is swung so that thecurved ends of the contacts 111 and 142 thereof are disposed inopposition to the curved ends of the contacts 116, 117, 11S, 119 of saidcircuits, and the switch is then slidably moved in the elongatedfslot139 for its contacts to abut against the said contacts of this circuit.T he circuit 12'0 will then be closed from one of the correspondingpoles of each of the batteries so` that the current will hetransn'littcd over the wirey 112 to the Contact 110, through the contact112 of the s.\itclithrongh contact 119. over wire 122, throughthe metaltube 100 of the relie-'ton through the lamps 98, through the plate 102,over the wires 121 and 120, through the contacts 118, through thecontact 141 of the switch, through the contact 117, and over the wire114 'to the correspor'idl in stond pole of' each of the batteries. i enit is desired to light the lamps by a currentI supplied over the circuit104 from a sliitahle source of supply other than the batteries 105 theplug 130 is inserted in the socket 123;v The switch 137 is then swungsothat the curved ends of the contacts 1111 and 143 thereof are disposedin opposed relation to thefeurved ends of thc contacts 126, 127, 133,135, and the switch is .slidably shifted in the elongated slot 139 forits contacts to abut against the said contacts of this circuit, 'l'hecircuit will then be closed from the' source of supply over the wire131, through Contact 1213, through contact 141.01: the switch, throughContact 13?, over ,wire 134, through the tube 11)() of the reflector,through the lamps 98, through the plate 102, over wires 121 and 1516.through contact 127, to contact 142 of the switch, to contact 127, andover the wire 132 leading from the source of supply. In this mannereither of the electric circuits y103 and 101 may be separately employedfor lighting the lamps 118 when the machine is used as a projectingapparatus for displaying the pictures of the strip upon a screen. Thus asimple. and efficient machine may be produced which is easilyconvertible from a camera to a projecting apparatus whereby animatedpictures of objects may be photographed in succession on a strip andafterward displayed on ii, screen without the use of two separatemachines as is incident to the methods usually employed in theproduc-thin and exhibition of moving pictures. y

In the foregoing description, I have cmbodied tl'e, preferred form of'my invention, but I do not wish to be understood as limiting myselfthereto, as I am aware that modifications may be made therein withoutdeparting from they principle, or sacrificing any of the advantages ofthis invention, therefore I reserve to myself the right to ma he suchchanges as fairly fall within the scope of theI appended claims.
